Glossary: Safeword – A codeword a bottom can use to force BDSM activity to stop – used especially in scenes which may involve consensual force. Glossary: Top: Person 'doing the action' (contrast with bottom – person receiving the action.) Not to be confused with Dom which is the person who 'puts the scene together'. A male Dom could enjoy CBT and tell a sub what they are to do. In this case the Top is the submissive (following the direction of the Dom) and the bottom is the Dom (receiving the attention of the top).
